The new stair in the University of Sydney Business School required the procurement and fixing of 2mm-thick silky oak timber veneer cladding to the faces and soffit of a spiral stair. Works included concealed fixings and LED lighting to the balustrade. Works were managed and coordinated around third-party trades who worked on the stair treads and adjacent building works. A separate scaffold was used specifically for the stair cladding. The stair was designed and shaped in a way that excluded traditional set out. A 3D scanner was used and a specialist from Germany was engaged for this part of the work. This was a complex project and the five-storey spiral stair, reducing in diameter as it gets higher, was faced with veneered panels in an exacting and carefully pre-planned manner.
